Chris Douglas updated HADOOP-3031:
----------------------------------
Attachment: 3031-1.patch
+1 for hudson checking for javac warnings as part of the compile-core-test
target
We should fix both warnings in this patch. We can strip EmptyInputFormat of
even more information, rather than refining it to fit with SequenceFile's
constraints, which seems to match the spirit of the test. It's not possible to
fix the last warning in TestReduceTask, because WritableComparators are not
generic types (i.e. WritableComparator.get(Class\<T\> c) does not return a
WritableComparator\<T\> that can satisfy the RawComparator\<KEY\> formal in the
ValuesIterator cstr), so we can only suppress the warning.
> Remove compiler warnings for ant test
